I guess some of guys forgot the part in ds9 when they said Dax wasn't going to sto vo kor because she didn't die in a glorious battle. So they had to win a battle in her name. O'brien also pointed out she wasn't going to sto vo kor because she didn't eat the heart of one of her enemies. It wasn't just something specific to Kor. These are apparently requirements. Canon, stated in multiple episodes of ds9.
